§ 109. Liability for damage to property in transit. Every common carrier shall, upon demand, issue either a receipt or bill of lading for all property delivered to it for transportation. No contract, stipulation or clause in any receipt or bill of lading shall exempt or be held to exempt any common carrier from any liability for loss, damage or injury caused by it to property from the time of its delivery for transportation until the same shall have been received at its destination and a reasonable time shall have elapsed after notice to consignee of such arrival to permit the removal of such property. Every common carrier shall be liable for all loss, damage or injury to property caused by delay in transit due to negligence while the same is being carried by it, but in any action to recover for damages sustained by delay in transit the burden of proof shall be upon the defendant to show that such delay was not due to negligence. Every common carrier shall be liable for loss, damage and injury to property carried as baggage whether in connection with the transportation of the owner or not, up to the full value and regardless of the character thereof, but the value in excess of one hundred and fifty dollars shall be stated upon delivery to the carrier, and a written receipt stating the value shall be issued by the carrier, who may make a reasonable charge for the assumption of such liability in excess of one hundred and fifty dollars and for the carriage of baggage exceeding one hundred and fifty pounds in weight upon a single ticket or receipt. Nothing in this section shall deprive any holder of such receipt or bill of lading of any remedy or right of action which he has under existing law.
